Question

triangles WSR and TVR are similar. Find x

Answer 1

Triangles WSR and TVR are similar.
The order of letters of each triangle are important when you say they are similar.
It means WS / TV = SR / VR = WR / TR

Answer 2

WS is the first two letters of the first triangle, TV is the first twi letters of the second triangle. SR is the second and third letter and so is VR. ...

Answer 3

So just plug in the values:

WS / TV = SR / VR = WR / TR

10 / 18 = not known = (x+2) / (x + 6)
10/18 = (x+2)/(x+6)
cross multiply:
10(x+6) = 18(x+2)
solve for x.

Answer 5

Yes x = 3.
